Abstract

Hormones have been suggested to play a prominent role in the control of callus growth. In this paper, with the method of indirect enzyme-linked immunosorbent assays (ELISA), we investigated the induction effect of soundwave on the dynamic change of endogenous indole-3-acetic acid (IAA) and abscisic acid (ABA) in vitro during the differentiation process of Chrysanthemum synchronized mature Callus. These experiments showed that groups treated by optimal soundwave (1.4 kHz, 0.095 kdb) had significantly higher IAA levels and lower ABA than that of the control, which had been implicated activation of endogenous IAA and inhibition of ABA. Through the biochemical analysis, it revealed that the increased level of IAA as well as decreased levels of ABA correlated with soundwave stimulus. High rate of IAA/ABA was favorable to development of the callus and differentiation of mature callus. We conclude that soundwave contributes to endogenous hormone as well as the control of callus growth.
